What is a murmur of the heart?

Overview. Heart murmurs are sounds — such as whooshing or swishing — made by turbulent blood in or near your heart. Your doctor can hear these sounds with a stethoscope. A normal heartbeat makes two sounds like “lubb-dupp” (sometimes described as “lub-DUP”) when your heart valves are closing.

How do you classify a murmur?

Murmurs can be classified by seven different characteristics: timing, shape, location, radiation, intensity, pitch and quality.

  1. Timing refers to whether the murmur is a systolic or diastolic murmur.
  2. Shape refers to the intensity over time; murmurs can be crescendo, decrescendo or crescendo-decrescendo.

What are the four types of heart murmurs?

Types of murmurs include the following:

  • Systolic murmur. A heart murmur that occurs during a heart muscle contraction.
  • Diastolic murmur. A heart murmur that occurs during heart muscle relaxation between beats.
  • Continuous murmur. A heart murmur that occurs throughout the cardiac cycle.

What causes a heart murmur?

A heart murmur is an extra noise heard during a heartbeat. The noise is caused when blood does not flow smoothly through the heart. Heart murmurs can be innocent (harmless) or abnormal (caused by a heart problem). Some causes are fever, anemia, or heart valve disease.

What do murmurs mean?

The “murmur” is the sound of blood flowing. It may be passing through an abnormal heart valve, for instance. Or it may be that a condition makes your heart beat faster and forces your heart to handle more blood quicker than normal.

What are the two types of heart murmurs?

What are the different types of murmurs?

  • Systolic murmur. This happens during a heart muscle contraction.
  • Diastolic murmur. This happens during heart muscle relaxation between beats.
  • Continuous murmur. This happens throughout the cardiac cycle.

What is murmur and its types?

Types of murmurs include: Systolic murmur. This happens during a heart muscle contraction. Systolic murmurs are divided into ejection murmurs (due to blood flow through a narrowed vessel or irregular valve) and regurgitant murmurs (backward blood flow into one of the chambers of the heart). Diastolic murmur.

What is the treatment for heart murmur?

Surgeries for heart murmurs often include valve repair and valve replacement. These surgeries treat the underlying valve problems in your heart that are causing the murmur. If you do need surgery, your cardiothoracic surgeon will try to make sure your surgery is as minimally invasive as possible.

Where do you hear heart murmurs?

Mitral murmurs are best heard at the apex and radiate to the axilla. Mitral sounds can be accentuated with the patient in the left lateral position. Hence, to listen to a mitral murmur, first listen to the apex, then listen round to the mid-axillary line at the same level.

What are the grades of heart murmurs?

GRADES. Systolic murmurs are graded on a six-point scale. A grade 1 murmur is barely audible, a grade 2 murmur is louder and a grade 3 murmur is loud but not accompanied by a thrill. A grade 4 murmur is loud and associated with a palpable thrill.

What does it mean if you have a heart murmur?

A heart murmur is an extra or unusual sound which may be heard. It may be caused by a related heart problem, but often there is no cause at all. Heart murmurs are quite common in children. They are sometimes described as ‘innocent’ heart murmurs. This is because they are usually harmless and not caused by a problem with the heart.

What is a heart murmur and is it dangerous?

Heart murmurs are classified as either “ innocent ” or “ abnormal .” Innocent heart murmurs aren’t dangerous and generally require no medical intervention. They can be caused by anemia, fever or hyperthyroidism, among other reasons. Chances are pretty good someone you know has or has had an innocent heart murmur.

What causes a heart murmur and how does it sound?

These sounds are caused by the closing of valves inside your heart. If there are problems in your heart, there may be additional or abnormal sounds. The most common abnormal heart sound is a heart murmur. A murmur is a blowing, whooshing, or rasping sound that occurs during your heartbeat.

What does a heart murmur feel like?

A typical heart murmur sounds like a whooshing noise, and according to the American Heart Association (AHA), it usually feels like a very subtle extra pulse. Heart murmurs are common, especially among young children. They are usually normal and are called innocent heart murmurs.
